Debugging
TORQUE supports a number of diagnostic and debug options including the following:
PBSDEBUG environment variable - If set to 'yes', this variable will prevent pbs_server, pbs_mom, and/or pbs_sched from backgrounding themselves allowing direct launch under a debugger. Also, some client commands will provide additional diagnostic information when this value is set.
PBSLOGLEVEL environment variable - Can be set to any value between 0 and 7 and specifies the logging verbosity level (default = 0)
PBSCOREDUMP environment variable - If set, it will cause the offending resource manager daemon to create a core file if a SIGSEGV, SIGILL, SIGFPE, SIGSYS, or SIGTRAP signal is received. The core dump will be placed in the daemon's home directory ($PBSHOME/mom_priv for pbs_mom and $PBSHOME/server_priv for pbs_server).
To enable core dumping in a Red Hat system, you must add the following line to the /etc/init.d/pbs_mom and /etc/init.d/pbs_server scripts:
export DAEMON_COREFILE_LIMIT=unlimited
NDEBUG #define - if set at build time, will cause additional low-level logging information to be output to stdout for pbs_server and pbs_mom daemons.
tracejob reporting tool - can be used to collect and report logging and accounting information for specific jobs (for more information, see Using "tracejob" to Locate Job Failures).
PBSLOGLEVEL and PBSCOREDUMP must be added to the $PBSHOME/pbs_environment file, not just the current environment. To set these variables, add a line to the pbs_environment file as either "variable=value" or just "variable". In the case of "variable=value", the environment variable is set up as the value specified. In the case of "variable", the environment variable is set based upon its value in the current environment.
